Abstract
The electronic absorption spectra of C-60 and C-70 are simulated with the help of semiempirical quantum-chemical calculations. It is shown t hat the main features observed experimentally are satisfactorily repro duced by the calculations. Double-excited configurations are necessary to correctly describe the lowest excited states of C-70 and dipole-al lowed excited states are computed to be very close to the lowest excit ed state S-1. Preliminary results on the simulation of the fluorescenc e spectrum of C-70 are discussed.
